Dit gedeelte, van naar mA, is berekend met de formule: IB = IC : HFE. Where: Ib is the base current, Vb is the base bias voltage, Vbe is the base-emitter volt drop (v) and Rb is the base input . Electronics Tutorial about the PNP Transistor, the PNP Transistor as a switch and how the PNP Transistor works including its Common Emitter Configuration. Een zelfde formule geldt voor de effectieve stroom in afhankelijkheid.

De spanningsdeler aan de basis van de transistor bestaat uit de weerstanden. How much power the transistor dissipates depends on the voltage. Ze kunnen de formules vanbuiten maar daar stopt het.

How to calculate Ib of a Transistor Circuit. The equation to solve for Ie is: formula to calculate the base current Ib of a transistor. If the β of the transistor is known, α can be calculated very easily by the formula: Formula for alpha of transistor. Example If β of a transistor is 10 calculate the α . Transistors are used to amplify current and so in an examination you could be.
